Example Embodiment

[0011]In the following, the structure of the planetary wheel axle of the drive axle of the loader of the present invention will be further described in detail with reference to the drawings and specific embodiments.

[0012]figure 1 As shown, the wheel side planetary wheel shaft structure of the drive axle of the loader of the present invention includes a wheel side end cover 1 and a planetary wheel shaft 2. The planetary wheel 4 is mounted on the planetary wheel shaft 2 through a roller bearing assembly 6, and the roller bearing assembly 6 passes through a retaining ring 5. The limit is to ensure that the roller bearing assembly 6 does not loosen; the wheel side end cover 1 and the planetary wheel shaft 2 adopt a split type. The planetary wheel shaft 2 is a separate flange type and is forged with 20CrMnTi material and then carburized and quenched. A plurality of evenly distributed screw holes are arranged on it, which are fixed on the wheel end cover 1 by screws 3.

Abstract

The invention discloses a wheel edge planet wheel shaft structure of a loader drive axle. The wheel edge planet wheel shaft structure comprises a wheel edge end cover and a planet wheel shaft, a planet wheel is installed on the planet wheel shaft through a roller bearing assembly, and the roller bearing assembly is limited through a check ring so that it can be guaranteed that the roller bearing assembly cannot get loose; the wheel edge end cover and the planet wheel shaft are in a split type, and the planet wheel shaft is in an independent flange type; a plurality of screw holes which are uniformly distributed are formed in the wheel edge end cover, and are fixed on the wheel edge end cover through screws; and an independent flange type planet wheel shaft is formed by forging a 20CrMnTi material and then carrying out carburizing and quenching treatment, so that the rigidity is improved. The problems that in the prior art, the manufacturing cost is high due to the fact that four standcolumns of the wheel edge end cover need to be forged and formed many times, and the failure rate is high due to stress concentration easily caused by roots of the four stand columns of the wheel edgeend cover are solved.

Description

technical field [0001] The invention relates to a wheel side reducer assembly of a drive axle of a loader, in particular to a wheel shaft structure of a wheel side of a loader drive axle. Background technique [0002] At present, the wheel side reducers of domestic loader drive axles all adopt NGW structure, which is used to transmit large torque. Among them, the wheel side end cover of a loader is a forged steel structure, and the wheel side end cover is equipped with four columns. The four pillars replace the planetary wheel shafts of ordinary structure, and the planetary wheels are assembled on the pillars of the wheel end cover with roller bearing assemblies for torque transmission. The structure of the wheel-side planetary wheel axle of the drive axle of the loader has the following defects: First, the four columns of the wheel-side end cover are made of forging. The roots of the four columns of the side end cover are prone to stress concentration and high failure rate...
